Description

Technical Field

[0001] This utility model relates to the field of mold forming, and more specifically, to a vacuum device for controlling the humidity gradient inside the mold. Background Technology

[0002] Mold forming technology originated from the urgent need for large-scale and precision production in industrial manufacturing. Early manual manufacturing was inefficient and inconsistent, making it difficult to meet the requirements of industries such as machinery and automobiles for the mass production of complex parts. With the advancement of materials science and machining technology, mold forming has enabled rapid product replication through standardized mold cavities, which not only greatly improves production efficiency but also allows for precise control of dimensional accuracy and surface quality. Its development has driven the transformation of manufacturing towards automation and integration, becoming one of the core processes in the modern industrial system.

[0003] In the precision mold forming process, different functional areas exhibit significant differences in their sensitivity to humidity. If the humidity inside the mold differs too much from the humidity required for mold formation, localized moisture accumulation can easily occur, leading to abnormal material curing and defects such as bubbles and cracks, severely impacting product yield and structural strength. To address this, a vacuum device for controlling humidity gradient inside the mold is proposed. Utility Model Content

[0008] As a preferred technical solution of this utility model, the partitioning component includes three partition plates fixedly installed inside the housing. The three partition plates are arranged regularly at equal intervals inside the housing. Four humidity sensors are fixedly installed at equal intervals on the side of the housing away from the support base. A switch hole is opened on one side of the housing.

[0010] As a preferred technical solution of this utility model, an inclined surface block is fixedly installed at the bottom inside the shell, and four water outlet holes are opened on the side of the shell away from the support base. The four water outlet holes are arranged in a horizontal array, and a water outlet pipe is fixedly connected inside the water outlet hole.

[0011] As a preferred technical solution of this utility model, the shell has three observation holes on the side away from the support base, the three observation holes are arranged in a horizontal array, and observation glass is fixedly installed inside the observation holes.

[0012] As a preferred technical solution of this utility model, a sealing strip is provided on the top of the O-shaped sliding block, and rubber sealing layers are fixedly connected to both sides of the barrier plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up humidification and vacuum components and partitioning components, during use, the mold is placed inside the shell, and pure water is placed inside the water tank. The vacuum pump reduces the partial pressure of water vapor, thus controlling the humidity. The water in the water tank is atomized and sprayed out through the atomizing nozzle. Water vapor partially condenses under low pressure, but the humidity is maintained by continuous humidification through the atomizing nozzle. The opening and closing of the atomizing nozzle can be controlled individually to humidify local areas. The humidity requirements for mold forming are met by dividing the shell into four areas through partition plates, which are independently isolated to facilitate different humidity levels in different areas. The humidity sensor measures the real-time humidity of each area so that the user can operate accordingly based on the data. The switch hole allows the user to easily add materials into the mold. The switch hole is closed by O-ring sliding block and baffle plate to form a closed space for the vacuum pump to work.

[0016] 2. By setting up a drying component, the desiccant bag can help reduce humidity during use, preventing excessive humidity from affecting the molding process. A micro motor drives the gears and the sliding plate connected to the rack and pinion to rise and fall. Lowering the sliding plate can prevent the desiccant bag from contacting the environment inside the shell and causing any impact. Raising the sliding plate will allow the desiccant bag to begin absorbing moisture and reducing the humidity inside the shell. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figure 1 As shown, this embodiment proposes a vacuuming device for controlling in-mold humidity gradient, including a base 1. The base 1 is provided with a humidification and vacuuming component 2 for vacuuming and local humidification during the mold forming process. The humidification and vacuuming component 2 is provided with a partitioning component 3 for forming a humidity gradient and a drying component 4 for moisture absorption and drying.

[0029] like Figure 6As shown, the humidification and evacuation assembly 2 includes a housing 201 welded to the top of a base 1. A support base 202 is welded to the top of the base 1, and a vacuum pump 203 is fixedly installed on the top of the support base 202. The vacuum pump 203 is used to extract air from the inside of the housing 201 to reduce air pressure and thus control humidity. An evacuation box 204 is fixedly installed on the side of the housing 201 near the vacuum pump 203. Three evacuation holes 205 are opened on the side of the housing 201 near the evacuation box 204. The evacuation box 204 and the evacuation holes 205 are used to form a space for the vacuum pump 203 to extract air. One end of a connecting pipe 206 is fixedly connected to the side of the evacuation box 204 near the vacuum pump 203, and the other end of the connecting pipe 206 is fixedly connected to the vacuum pump 203. A water supply pipe 20 is fixedly installed on the top of the housing 201. 7. The water supply pipe 207 is used to connect the purified water in the water storage tank 209 to the atomizing nozzle 208 for use. Several atomizing nozzles 208 are connected to the bottom of the water supply pipe 207. The atomizing nozzles 208 are used to continuously maintain humidity when the humidity is too low. The water storage tank 209 is fixedly installed on the top of the water supply pipe 207. When in use, the mold is placed inside the housing 201, and purified water is put into the water storage tank 209. The vacuum pump 203 draws a vacuum to reduce the water vapor partial pressure and control the humidity. The water in the water storage tank 209 is atomized and sprayed out through the atomizing nozzles 208. The water vapor partially condenses under low pressure, but the humidity is maintained by continuous humidification through the atomizing nozzles 208. The humidity requirement for mold forming is met by individually controlling the opening and closing of the atomizing nozzles 208.

[0030] like Figure 3As shown, the partitioning component 3 includes three partition plates 301 fixedly installed inside the housing 201. The three partition plates 301 are arranged regularly at equal intervals inside the housing 201. The partition plates 301 are used to partition the housing 201, so that the humidity of each area does not affect each other, thereby forming a humidity gradient. Four humidity sensors 302 are fixedly installed at equal intervals on the side of the housing 201 away from the support base 202. The humidity sensors 302 are used to accurately reflect the humidity. A switch hole 303 is opened on one side of the housing 201. The switch hole 303 is used to open and facilitate internal operations such as mold injection by the user. An O-shaped sliding block 304 is welded to one side of the housing 201. The O-shaped sliding block 304 and the switch hole 304 are connected together. Corresponding to position 03, an isolation plate 305 is slidably connected inside the O-shaped sliding block 304. The isolation plate 305 is used to close the switch hole 303 to form a closed space. A display panel 306 is fixedly installed on the side of the housing 201 away from the isolation plate 305. In use, the housing 201 is divided into four areas by the partition plate 301 for independent isolation, so that different areas can form different humidity. The humidity sensor 302 measures the real-time humidity of each area so that the user can make corresponding operations based on the data. The switch hole 303 makes it convenient for the user to add materials into the mold. The O-shaped sliding block 304 cooperates with the isolation plate 305 to close the switch hole 303 to form a closed space so that the vacuum pump 203 can work.

[0031] like Figure 6As shown, the drying assembly 4 includes eight drying holes 401 formed on both sides of the housing 201. The eight drying holes 401 are arranged in a four-by-four array on both sides of the housing 201. The drying holes 401 facilitate the contact of the desiccant bag 404 with the environment inside the housing 201. Eight placement shells 402 are welded to both sides of the housing 201, and the placement shells 402 correspond to the positions of the drying holes 401. A middle plate 403 is welded inside the placement shell 402, which supports the micro motor 405. A desiccant bag 404 is placed inside the placement shell 402 to reduce the humidity inside the housing 201 and prevent excessive humidity. The desiccant bag 404 is located at the bottom of the middle plate 403, and the micro motor 405 is fixedly mounted on the top of the middle plate 403. The micro motor 405 is used to provide power. A gear 406 is fixedly installed at the output end of the micro motor 405. A sliding plate 407 is slidably connected in the gap between the intermediate plate 403 and the housing 201. The sliding plate 407 is used to isolate the desiccant bag 404. A rack 408 is fixedly installed on the side of the sliding plate 407 near the micro motor 405. The gear 406 and the rack 408 mesh. In use, the desiccant bag 404 can help reduce humidity and avoid excessive humidity from affecting the molding. The micro motor 405 rotates to drive the gear 406 and the sliding plate 407 connected to the rack 408 to rise and fall. Lowering the sliding plate 407 can prevent the desiccant bag 404 from contacting the environment inside the housing 201 and causing an impact. Raising the sliding plate 407 can start the desiccant bag 404 to absorb and reduce the humidity inside the housing 201.

[0032] like Figure 3 and Figure 6 As shown, an inclined block 5 is fixedly installed at the bottom inside the housing 201. Four water outlet holes 6 are opened on the side of the housing 201 away from the support base 202. The four water outlet holes 6 are arranged in a horizontal array. A water outlet pipe 7 is fixedly connected inside the water outlet hole 6. A regulating valve 8 is provided around the water outlet pipe 7. When in use, the vacuum pump 203 operates to generate a low-pressure environment. Some water vapor condenses into liquid and collects at the bottom inside the housing 201. The liquid is further collected by the inclined block 5. After the work is completed, the regulating valve 8 is opened to allow the liquid inside the housing 201 to flow out, so as to avoid the housing 201 from aging due to prolonged contact with liquid.

[0033] like Figure 3 As shown, the housing 201 has three observation holes 9 on the side away from the support base 202. The three observation holes 9 are arranged in a horizontal array. An observation glass 10 is fixedly installed inside the observation holes 9. When in use, the user can quickly understand the internal situation of the housing 201 through the observation glass 10 and take appropriate action.

[0034] like Figure 3As shown, the top of the O-shaped sliding block 304 is provided with a sealing strip 11, and the two sides of the barrier plate 305 are fixedly connected with rubber sealing layers 12. In use, the sealing strip 11 is used for sealing, and the rubber sealing layers 12 are used for further sealing of the barrier plate 305 to prevent air circulation from affecting the operation of the vacuum pump 203.

[0035] like Figure 4 As shown, a protective shell 13 is fixedly installed on the top of the support base 202. The protective shell 13 is used in conjunction with the vacuum pump 203. Eight ventilation holes 14 are provided on both sides of the protective shell 13. During use, the protective shell 13 protects the vacuum pump 203 to prevent damage caused by collision. The ventilation holes 14 facilitate the heat dissipation and ventilation of the vacuum pump 203.

[0036] Specifically, the vacuum device for humidity gradient control within the mold is used as follows: the mold is placed inside the housing 201, pure water is placed inside the water tank 209, and the vacuum pump 203 draws a vacuum to reduce the partial pressure of water vapor, thus controlling the humidity. The water in the water tank 209 is atomized and sprayed out through the atomizing nozzle 208. Water vapor partially condenses under low pressure, but humidity is maintained by continuous humidification through the atomizing nozzle 208. Localized humidification is achieved by individually controlling the opening and closing of the atomizing nozzle 208, thus controlling the humidity requirements for mold forming (e.g., ...). Figure 6 As shown), the housing 201 is divided into four areas by the partition plate 301, which provides independent isolation and allows different humidity levels to be formed in different areas. The humidity sensor 302 measures the real-time humidity of each area so that the user can make corresponding operations based on the data. The switch hole 303 allows the user to easily add materials into the mold. The O-ring slider 304, in conjunction with the barrier plate 305, closes the switch hole 303 to form a closed space so that the vacuum pump 203 can work (e.g., Figure 3 As shown), the desiccant bag 404 helps reduce humidity, preventing excessive humidity from affecting molding. A micro motor 405 rotates, driving the gear 406 and the sliding plate 407 connected to the rack 408 to rise and fall. Lowering the sliding plate 407 prevents the desiccant bag 404 from contacting the environment inside the housing 201 and causing any impact. Raising the sliding plate 407 allows the desiccant bag 404 to begin absorbing moisture, reducing the humidity inside the housing 201 (e.g., ...). Figure 6 (As shown).

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
